Forgetting that BC exists entirely. If you search "Kei" on Craigslist Vancouver, there's currently 37 postings, and they're constantly being imported here. I see them in Washington as well, although those may be Canadians just visiting.
A notable difference being in Canada you can import vehicles at 15 years old rather than 25. There is a decent flipping trade in Vancouver to import JDM vehicles while they are Canadian eligible but not US, hang on to them for a while, then sell them south once the 25 years are up.
